Blue Cross Blue Shield of Massachusetts, the state's largest commercial health insurer, is rolling back its coverage of pricey GLP-1 drugs such as Ozempic and Wegovy for weight loss. The insurer says it would continue covering GLP-1 medication for subscribers with diabetes. Employers that provide their workers with health insurance can also choose to pay extra if they'd like to include GLP-1 for weight loss coverage in their health plans — or opt out entirely.
